AMD® Sempron™ SI-42

The AMD Sempron SI-42 is a laptop processor with 1 cores and 1 threads. It launched in 2008. Rated TDP is 25 W.

The AMD Sempron SI-42 scores 637 in single-core performance and 245 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 395 for overall performance, 1,051 for productivity performance, 1,281 for creator performance, 224 for engineering performance and 1,972 for gaming performance. Its multi-core throughput works out to 245 per core, 245 per thread and 10 per watt. Its computed efficiency index is 79. Its performance index is 5, so its overall performance is 95% below the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the AMD Sempron SI-42 scores 612 in integer math, 569 in floating-point math, 6,171 in compression, 94 in cryptography, 31 in physics simulation, 80 in vector SIMD, 1 in the prime sieve and 895 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 99% below in integer math, 99% below in floating-point math, 97% below in compression, 99% below in cryptography, 97% below in physics simulation, 99% below in vector SIMD, 99% below in the prime sieve and 96% below in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The AMD Sempron SI-42 has 1 physical core and runs 1 logical thread. It does not use a hybrid performance and efficiency core layout. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 2.10 GHz.

The AMD Sempron SI-42 is a laptop processor and belongs to the AMD Sempron family. It launched in 2008.

The AMD Sempron SI-42 has 128 KB of L1 cache and 512 KB of L2 cache. That adds up to about 0.6 MB of cache, or 0.63 MB per core. Each core has 512 KB of private L2 cache.

The AMD Sempron SI-42 has a 2-level cache hierarchy: L1 at 128 KB and L2 at 512 KB. L2 is the largest level and makes up about 80% of the cache listed here.

The AMD Sempron SI-42 has a rated TDP of 25 W.
